Geometric Dissections

Author : Gavin Theobald

Last update: 11th June 2026

This website is a listing of 786 different geometric dissections. The majority I have discovered myself.

These are, as far as I know, all the best solutions. If you know of any better solutions, either requiring fewer pieces or removing the need to turn over pieces, then please let me know.
